Registered Dental Hygienist
Laura has been a practicing dental hygienist since 2000. She graduated from Marquette University where she earned a Bachelor of Science degree in dental hygiene. After graduation, Laura engaged in community dentistry by completing a 1-year volunteer program with the Capuchin Franciscan Volunteer Corp in Washington DC. During this time, Laura worked with low-income minority residents in an established urban dental clinic. Based on the impact this program had on her, Laura remained in the D.C. area for an additional 3 years serving both private and clinic-based patients.

In late 2004, Laura moved back to her hometown of Chicago and joined Dr. Barr’s practice soon after. She has enjoyed her time at the office and is grateful to have the continued opportunity to work with skilled and compassionate dentists that care deeply about patient care and workplace engagement, as well as practicing with the most beneficial dental technology available.

In her spare time, Laura enjoys being outside either running, cycling or tending to her garden. However, the most fun she has is simply spending time with her husband, Todd and daughter, Alexandra.
